Description

Technical Field

[0001] This utility model belongs to the field of battery box manufacturing technology, and in particular relates to a battery box production line. Background Technology

[0002] The existing battery box frame is mainly composed of front, rear, left, and right side panels. The left and right side panels have supporting edges on their inner sides. The four side panels are connected at 45-degree angles by welding through the cuts to form right-angled edges. Similarly, brackets and aluminum plates need to be set on both sides of the frame. In current production lines, aluminum plates are pre-installed on the brackets, and the frame can be directly assembled during welding. However, aluminum plates are prone to deformation due to their material properties, which may cause damage during material turnover, pre-welding positioning and clamping, and post-welding unloading, thus affecting product quality.

[0003] Similarly, weld milling equipment is set up in the production line to mill the weld points flat. However, this only applies to the welded area, and the rest of the overall part is not processed. This may cause problems with subsequent dimensions, thereby affecting the probability of defective products. Summary of the Invention

[0004] The purpose of this utility model is to provide a battery box production line. By adding a bracket welding station, the welding of the bracket and aluminum plate can be integrated into the production line, avoiding the problems of bumps and deformation during transportation, turnover and movement caused by pre-setting. The design of the assembly milling and drilling station allows the assembly part to be milled, improving the surface quality, avoiding subsequent dimensional problems, and further improving the product precision and quality. By adding stud welding and manual riveting, the bolts at the mounting holes can be pre-processed, thereby improving production efficiency.
